Spring Boot 3.2 Is End-of-Life: What That Actually Means for Your Applications

Spring Boot 3.2 has officially reached end of life.

As of December 31, 2025, both open-source support and commercial support have ended. No more security patches. No bug fixes. No guarantees.

If you’re still running Spring Boot 3.2 in production, you’re now operating on unsupported infrastructure—whether you realized it or not.

This post breaks down:

• What Spring Boot 3.2 EOL really means
• Why “it still works” is not a risk strategy
• The hidden security, compliance, and procurement impact
• How HeroDevs provides a safe, forward-compatible path without forcing a rushed upgrade

‍

Spring Boot 3.2 EOL: The Facts

Spring Boot follows a predictable lifecycle. Each release receives a fixed window of maintenance before support ends permanently.

For Spring Boot 3.2:

• OSS support ended: December 31, 2024
• Spring Enterprise support ended: December 31, 2025
• No future CVE patches will be released upstream
  
  

This isn’t a pause. It’s a hard stop.

From this point forward, any newly discovered vulnerability in Spring Boot 3.2 will remain unpatched forever unless you take action.

‍

Why End-of-Life Is a Bigger Deal Than Teams Expect

Most engineering teams don’t feel EOL immediately. Applications keep running. Deployments still succeed. Nothing breaks overnight.

That’s precisely why EOL risk is so dangerous.

‍

Security Exposure Becomes Permanent

Once a framework is EOL:

• CVEs continue to be discovered
• Exploits continue to evolve
• Fixes stop coming
  
  

Security teams can’t patch what doesn’t exist. Vulnerability scanners flag issues with no remediation path. Over time, that turns into accepted risk—or worse, ignored risk.

‍

Compliance and Audit Risk Creeps In

Unsupported software regularly shows up in:

• SOC 2 findings
• Internal risk assessments
• Enterprise procurement questionnaires
  
  

“Why are you running unsupported components in production?” is not a question you want to answer with “we plan to upgrade eventually.”

‍

Forced Upgrades Are Rarely Planned Upgrades

Spring Boot upgrades aren’t always trivial—especially when tied to:

• Jakarta namespace changes
• Java runtime constraints
• Third-party dependency compatibility
• Embedded frameworks and vendor software
  
  

When teams delay action until an incident or audit forces their hand, the result is rushed migrations, unplanned outages, and blown timelines.

‍

‍

“Just Upgrade to a Newer Spring Version” Isn’t Always Realistic

Yes, modern versions of Spring Boot exist.

But for many organizations, upgrading immediately isn’t feasible due to:

• Platform certification timelines
• Vendor dependencies locked to 3.2
• Regulated environments
• Large, distributed applications with long test cycles
  
  

Support lifecycles don’t always align with business realities. When they don’t, teams need a safe way to bridge the gap.

‍

‍

The Limits of AI-Assisted Migrations

AI-assisted migration tools are improving, but they are not a silver bullet for Spring Boot upgrades. 

While AI can help surface deprecated APIs or suggest mechanical changes, it struggles with the complexities of Spring applications, including custom configuration, deeply coupled dependencies, undocumented business logic, and environment-specific behavior. Automated migrations often overlook subtle runtime issues, security implications, and performance regressions that only become apparent under production load. 

For regulated or mission-critical systems, relying on AI to modernize a framework upgrade can introduce new risks rather than eliminate them—especially when teams are forced to migrate quickly due to end-of-life pressure, rather than following a controlled, validated plan.

How HeroDevs Solves the Spring Boot 3.2 EOL Problem

HeroDevs provides Never-Ending Support (NES) for end-of-life open-source software, including Spring-based ecosystems.

With HeroDevs NES for Spring Boot 3.2, you get:

Ongoing Security Patches

Critical and high-severity vulnerabilities are identified, patched, and released even after upstream support ends.

Drop-In Compatibility

No refactors. No rewrites. APIs and behavior remain consistent so your applications keep running as-is.

Forward Compatibility

HeroDevs ensures EOL software continues to run on modern JVMs, operating systems, and infrastructure, reducing future technical debt.

Compliance Coverage

NES gives security, audit, and procurement teams a clear support story without forcing immediate upgrades.

Time to Modernize on Your Terms

You regain control of your roadmap, rather than reacting to artificial deadlines.

‍

EOL Is Not a Failure—Ignoring It Is

Spring Boot 3.2 reaching end of life doesn’t mean your architecture is broken. It means the ecosystem has moved on.

The real risk comes from doing nothing.

Organizations that proactively address EOL software:

• Reduce security exposure
• Avoid audit surprises
• Protect uptime
• Modernize on a timeline that actually makes sense
  
  

‍

What to Do If You’re Still Running Spring Boot 3.2

If Spring Boot 3.2 is anywhere in your production stack, your next steps should be clear:

• Inventory where it’s used
• Assess security and compliance exposure
• Decide whether upgrading now is realistic
• If not, put supported coverage in place
  
  

HeroDevs exists for teams exactly in this situation.
